Answer:
True.
Explanation:
- Applying the definition of average velocity, we know that we can always write the following expression:
(1)
- By definition, Δx is just the displacement, and Δt is the time interval.
- So, just rearranging terms in (1), we get:
<span>D) The new force will be sixteen times greater than the original
This is because of the equation for gravitational force.
Distance is squared.</span>
